In 2022,Zhen, Jingsong; Du, Xian; Xu, Xiaohong; Li, Yihui; Yuan, Han; Xu, Dejing; Xue, Can; Luo, Yong published an article in ACS Catalysis. The title of the article was 《Visible-Light-Mediated Late-Stage Sulfonylation of Boronic Acids via N-S Bond Activation of Sulfonamides》.Electric Literature of C7H9NO2S The author mentioned the following in the article:
A visible-light-mediated late-stage arylation of N-S bonds in sulfonamides was developed with using readily available imines as sulfonyl radical source. Diverse complex sulfones could be synthesized by prefunctionalization and subsequent N-S bond arylation, demonstrating the advantages of using sulfonamides as sulfonylation reagents. Addnl., the mechanism research revealed that probably both EDA complex chem. and photoredox catalysis were responsible for the formation of sulfones. This methodol. characterized by broad substrate scope and simple reaction conditions also has high atom economy, since the aldehyde for the synthesis of imines could be recovered after workup of the reactions. In the experiment, the researchers used 4-Methylbenzenesulfonamide(cas: 70-55-3Electric Literature of C7H9NO2S)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. Amine, any member of a family of nitrogen-containing organic compounds that is derived, either in principle or in practice, from ammonia (NH3). Naturally occurring amines include the alkaloids, which are present in certain plants; the catecholamine neurotransmitters (i.e., dopamine, epinephrine, and norepinephrine); and a local chemical mediator, histamine, that occurs in most animal tissues.Electric Literature of C7H9NO2S
